Please make sure that your USB plug and USB port is clean 2. Error message shows up "Setting error! Fail to play the program!" or "Fail to play your program":

Please check the driver of VGA card and sound card Please make sure the hardware and software settings are correct, and try TV channel scanning again Please install Microsoft DirectX9.0C and Media Player 9.0 or higher version Might be due to poor signal quality so that DIGITAL TV can not receive enough data of program or received wrong data. It is a paid channel and you are not authorized to see

Make sure to use the latest DIGITAL TV software version for decoder. Register C:\Program Files\PC-TV\Common\Bin\claud.ax and CLVSD-dtv.ax again with regsvr32.exe in C:\Windows\System32.

3. Screen blacked out when playing or playback freezes on first picture. Find and install the latest VGA driver and DirectX 9.0C and check if any other DTV players are installed. If yes, remove them and uninstall all the filter drivers 4. Which format is recorded by DIGITAL TV? Why do I have problem with converting/burning this file? MPEG2.

You do not need to install additional drivers because it will install the built-in HID driver in your OS. 9. Remote control does not work Check remote control batteries. Check remote receiver: the red light on receiver will remain ON as it is getting signal from the remote control. Also, point your remote control to the receiver when in use. ATSC 1. Why cannot I lock any channels when auto-scanning?

Check whether the antenna connects to the device correctly. Check whether the signal in your area is strong enough.

2. When the pictures are not playing smoothly, Set application thread priority to “High” from System Setting. Enable “Max CPU power required on playback from System Setting. Enable “MPEG2 DxVA Accelerator” from System Setting.

3. Digital Cable : All digital Cable signal, including HDTV through cable, are controlled by the cable companies. They usually require additional “DCR” – Digital Cable Ready Equipment and a monthly fee in order to get digital HDTV signal through cable. Please contact your TV cable company on the details of “DCR” equipment. Digital TV support off the air ATSC digital broadcast, but does not support digital TV signal through cable at this time. For even better reception, you may attach the unit to a larger indoor or outdoor ATSC/HDTV antenna. By doing so, you may receive more ATSC channels and have few drop outs.
